When the sale of marijuana for recreational use became legal in Colorado and Washington last year -- and in Oregon this year -- a few predictions, both good and bad, were made about the outcome. Here's what has actually happened so far.

• Tax windfall: Colorado has taken in more than $86 million in cannabis taxes and fees this year, far more than for alcohol. Washington state is predicting $1 billion in marijuana taxes over the next four years. "All that money that was going to criminals and the hands of cartels is now being sent toward legitimate taxpaying businesses," said Morgan Fox of the Marijuana Policy Project.

• Freaking out on edibles: Overeager children and adults freaked themselves out by consuming too much marijuana at once; while pot is non-toxic and you'll always be OK, it can take you for a scary ride if you're not accustomed and dose high.

• No banking: Marijuana is now big business, but the big banks won't touch the money. Cannabis remains a Schedule I controlled substance under federal law, even in states where it is legal, and bankers fear prosecution.
